Share 'FrSky inverted TTL APM2'
Hi together, i want to use a D4R-II together with APM2, PPM and RSSI are no problem. What i want to connect as well is the serial port of RX and APM2 to send compressed GPS information over the FrSky data downlink to my antenna tracker. in principle i have that working, currently with an arduino pro mini evaluating an attached GPS sensor, compressing the GPS data and sending it over the downlink…
